Results:

After randomization 5 participants did not undergo their surgical intervention. Of the 40 initiating intervention (22M/18F; age 51±10 years; BMI 36.5±3.7 kg/m2; diabetes duration 9±5 years; HbA1c 8.2±1.2 on insulin) the proportion meeting the primary glycemic endpoint was achieved in 33 of IMWM (P=0.457). HbA1c reduction was similar between groups at both 3- and 12-months (-1.2±0.3 versus -1.0±0.3%, P=0.496).
